These red precision disk wheels have an outer diameter of 4 , a width of 0.23 , and utilize the 0.77 hub pattern. These simple wheels are ideal for any light robot that needs a basic disc for simple movement, and use a removable rubber ring for traction.

Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.
